Hetki is a log sauna. For a good reason.
Our saunas are built from logs made of certified spruce, grown slowly in the northern forests of Finland. Slow growth means tight-grained, strong wood, durable for a lifetime of enjoyment.
Logs are not just beautiful, they are also smart. Because the logs that we use are made from the tree’s core, the hardest and most resilient part, they have excellent insulating capacity, stay stable in shape, and make the sauna energy efficient. Spruce logs are breathable, withstand moisture, and age gracefully.
One of the greatest advantages of a log sauna is its thermal mass. As the solid log walls gradually warm up, they begin to radiate gentle heat of their own. Instead of feeling surrounded only by hot air, you feel enveloped by warmth. It's one of the reasons why a traditional log sauna feels so different.
Wood is natural, safe, and soothing for all senses. It carries the clean scent of Finnish forests and turns a sauna into a true haven of well-being.
Sauna is very much about health and well-being. Spruce, like other conifers, has long been known for its refreshing scent and beneficial effects on breathing and relaxation. Sauna, and namely a log sauna, is one of the best things you can do for your body and mind - boosting recovery, lowering stress, bringing happiness, and improving overall vitality.
Each log also has its own character - no two pieces are ever identical - giving every Hetki outdoor sauna a unique look that cannot be replicated.
The oldest saunas in Finland were, and still are, log saunas. So is Hetki.
